The Schneider Electric WATSNB‑80/4F1X1 is a dual power automatic transfer switch (ATS) designed for three‑phase low‑voltage power distribution systems. It ensures continuous electrical supply by automatically or manually transferring the load between two independent AC power sources (for example, utility mains and a standby generator). The device continuously monitors the status of both sources and initiates a transfer when the preferred source fails or returns, improving reliability for critical loads. The switch is suitable for industrial, commercial, and backup power applications.
